Abstract
An unwinding and/or winding device, particularly for awnings, comprising a rotating shaft rotatably coupled to a supporting element for the rotation of the rotating shaft around its longitudinal axis. A flexible element is also comprised, a portion of which is associable with a covering sheet to be tightened and fixed, at a first one of its ends, to the rotating shaft for the unwinding or winding of the same flexible element, respectively, from or onto the rotating shaft. The device also comprises a slider that moves with respect to the supporting element in parallel with the longitudinal axis of the rotating shaft and is kinematically associated with the rotating shaft by means of motion conversion elements for converting the rotary motion of the rotating shaft into a translational motion of the slider. During its unwinding or its winding, respectively, from or onto the rotating shaft, the flexible element is guided by the slider.
